Spatial streams are data streams that are sent out at the same time
on the same frequency in the wireless LAN. The transmission rate is
multiplied as a result.
All the parameters that are set while configuring IPSec are stored in
the router in the form of databases. These are the Security Policy
Database (SPD) and the Security Association Database (SAD). The
Security Policy Database lists the forms of data traffic that are to be
secured. Factors such as the source and destination address of the
data packet are used to do this.
With the speaker function, the people present in the room can listen
in to the telephone call.
A speed dial index (000...999) is assigned to every number in the
phone book. This speed dial index can be used to dial instead of the
long phone number.
A broadband access unit, commonly known as a splitter, is used to
split signals that come via a subscriber loop into data and telephone
lines.
The Secure Real-Time Transport Protocol (SRTP) is the variant of
the Real-Time Transport Protocol (RTP) that is encrypted using
AES.
Secure Shell (SSH) is a network protocol that can be used to estab-
lish an encrypted connection to a device's shell.
The Service Set Identifier (SSID) defines a wireless network that is
based on IEEE 802.11. The SSID is the network name of the wire-
less LAN. All the access points and clients that belong to the same
network use the same SSID. The SSID string can be up to 32 char-
acters long and is placed, unencrypted, in front of all packets. A cli-
ent uses SSID ANY to contact all the accessible access points. The
user is then shown all the available WLANs and he can select the
appropriate network. If an access point is used for different net-
works, each wireless network is given a separate MSSID (Multi Ser-
vice Set Identifier).
Secure Sockets Layer (SSL) is a protocol for data encryption. Since
version 3.1, the new term Transport Layer Security (TLS) has been
used. SSL is mainly used for HTTPS to encrypt the data transmis-
sion between web server and web browser.
